ABSTRACT
Fanconi-Bickel syndrome (FBS, OMIM 227810), a rare autosomal recessive disorder of carbohydrate metabolism, is caused by SLC2A2 (GLUT2) mutations. The study reported 3 cases of FBS who were confirmly diagnosed by SLC2A2 gene analysis. The three patients showed typical features like glycogen storage disease and proximal renal tubular nephropathy. Homozygous splice-site mutation IVS8+5G>C (c.1068+5 G>C) was found in patient A and homozygous nonsense mutation c.1194T>A (p.Tyr398X) in patient B. Patient C harboured a missense mutation c.380C>A (p.Ala127Asp) and a de novo insertion c.970dupT (p.324TyrfsX392) which was not inherited from her parents. Four mutations were identified in the 3 Chinese FBS patients. Except IVS8+5G>C mutation, the other 3 mutations were novel in Chinese population. To the best of our knowledge, patient C may be the first FBS case worldwide with de novo mutation.
